Clang command line to invoke LLVM flags

Hi there,

I was wondering if there is a way to set llc flags in clang?
Like
llc -mattr=+abc
How to set this subtarget in clang?

Thanks,

In general no, in practice most development flags (accessible from opt/llc) are available using -mllvm -flag=value

Like
llc -mattr=+abc

Target attributes are accessible using the cc1 flag "-target-feature”, the equivalent to llc -mattr=“+abc” should be:

clang -Xclang -target-feature -Xclang +abc
